How to test string palindrome in JavaScript

Created On: 02/10/2021

To test if a string is a palindrome or not, we can use several methods in javascript.

In the below example, we will reverse the string first and then compare both the original string and the reversed string. If both are the same then the string is a palindrome. See below code.

Copy
function checkPalindrom( text) {
    return text === text.split('').reverse().join('');
}

let text = "Hello World"
console.log(checkPalindrom(text));
// false

text = "madam"
console.log(checkPalindrom(text));
// true
